The news just broke that Apple has rejected the official upcoming Google Voice application, and stopped distributing the third party "GV" application, an app that was previously authorized. Read on for a quick commentary, from the point of view of not an Apple or Google fangirl, but from someone who genuinely appreciates VoIP SIP (even if Google Voice itself is not VoIP, read on). For those who have read my blog over the years, would probably remember my VoIP-related rants since 2005. UPDATE: A more direct, more personal, reply from me to Apple and AT&T.

While there's doubtless pressure on Apple from the networks, it's not enough to explain the situation. I can run SIP and Skype (not limited to wifi) on my Windows mobile phone with no problem. I suspect the same is true of Android.

The biggest problem with Google Voice is that it strategically terrifies the operators because it crosses over firmly into their territory. Google have the ability to make calls and texts (you can send free SMS messages) fundamentally cheaper forever and it encourages you to use your Google Voice number as opposed to your AT&T one, effectively disabling your relationship with AT&T. If it's cheaper then guess what people are going to use?

The latter was probably the real killer as it puts Apple's premium from AT&T at risk and the ending of the SMS cash cow in particular has them really worried.
